i didn't want to, at first i missed -dynamic-linker option and it was
the only somehow working variant.

i was using
CC=clang ./configure --prefix=...
and other things were default. no changes to any files.

i didn't use any build systems, just a shell script with commands. that
was just a hello world. i was able to compile it and if i encounter any
problems in future, i'll try the solution from FAQ.
btw, there was no link to this wiki from main site

i was investigating the possibility of using clang + musl for writing a
new program, not for porting existing software, so it may be possible to
avoid using some functions in reasonable scale, or change any component
in this bundle.
and does that bug affect a whole *alloc family or just calloc?
